The color of cirrhotic stools is determined by the complications of cirrhosis. If there are no complications, the color of cirrhotic stools is normal, which is the common yellow stool. If cirrhosis occurs, black stools may appear when the amount of bleeding is not large, and bloody stools may appear when the amount of bleeding is large. If a patient with cirrhosis has biliary stasis or liver cancer, the color of the stool may become lighter or turn gray. The color of stool in cirrhosis is also related to the food consumed. If too many green vegetables or blood clots have been consumed recently, the color of stool can be abnormal. The color of the stool is also related to the medication taken. If you take Chinese medicine or traditional Chinese medicine, the color of the stool may change to dark green or black.
